Strange id generated for few users, with multiple *


On a keycloak with around 230,000 users, some are identified by a weird id, made up of one or more stars, not always in the same place (examples: 4c1681c *************** * -b382f2a98c70 d ***************** - 97d1-25af0ed15dcc)

With this kind of users, the administration interface is unusable, and we cannot modify them via the API

We are using keycloak 10.0.1, with Java 8 in 25.151-b12

Has anyone encountered the same kind of problem?

thank you in advance
